What is the minimum clear opening measurement for exit doors as mandated by RA 9514?

The minimum clear opening measurement for exit doors, as mandated by Republic Act No. 9514, also known as the Fire Code of the Philippines, is set at 800 mm. This specification ensures that exit doors are sufficiently wide to allow quick and unobstructed evacuation during emergency situations, such as fires or other hazardous incidents.

A width of 800 mm helps facilitate the safe and timely exit of occupants, particularly in crowded scenarios where movement may be constricted. It balances the need for safety with the practical requirements of door design in terms of structure and usability while creating a minimal standard intended to enhance public safety.

It's important to note that the other options provided do not meet this necessary standard for an effective exit. Choices like 600 mm and 710 mm significantly fall short of the required dimensions, which could pose risks in emergency situations by potentially leading to overcrowding or delays. The higher measurement of 900 mm might provide additional clearance, but the law explicitly stipulates 800 mm as the baseline requirement for compliance.
